APT19 is a China-linked cyberespionage actor also known as Codoso, C0d0so0, and Codoso Team, with activity additionally associated with the Deep Panda name. Its targeting includes organizations in the United States, Australia, Canada, China, Denmark, India, and Italy. The actor uses spearphishing emails carrying weaponized Rich Text Format documents and macro-enabled Excel workbooks to deliver exploits and establish initial access. It has also distributed backdoored software, including serial-number generators, and used web shells on publicly accessible servers to access victim networks. Its tooling combines custom implants with publicly available frameworks such as PowerShell Empire. APT19 uses PowerShell to execute payloads and support command-and-control communications over HTTP and HTTPS. Associated Deep Panda activity includes the multistage, memory-resident MadHatter .NET implant, which uses PowerShell-initiated assembly loading to execute managed code without writing the payload to disk. Documented evasion techniques include Base64 obfuscation of commands and payloads and single-byte XOR encryption of malware strings. An APT19 malware variant establishes persistence by registering itself as a Windows service. Discovery activity includes using ping to identify remote systems and Tasklist to enumerate running processes.

A Chinese advanced persistent threat tracked as Deep Panda has been observed exploiting the Log4Shell vulnerability in VMware Horizon servers to deploy a backdoor and a novel rootkit on infected machines with the goal of stealing sensitive data. The latest set of attacks documented by Fortinet shows that the infection procedure involved the exploitation of the Log4j remote code execution flaw (aka Log4Shell) in vulnerable VMware Horizon servers.
This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
FireEye recently identified another targeted attack campaign that leveraged both the recently announced Internet Explorer zero-day, CVE-2013-1347, as well as recently patched Java exploits CVE-2013-2423 and CVE-2013-1493. ... If a visitor to one of these compromised website was running Internet Explorer 8.0 the malicious javascript would redirect them to a page at www[.]sunshop[.]com[.]tw hosting a CVE-2013-1347 exploit. ... The Internet Explorer (CVE-2013-1347) exploit code pulled down a “9002” RAT from another compromised site at hk[.]sz181[.]com.
The second jar file had a MD5 of 3fbb7321d8610c6e2d990bb25ce34bec and exploited CVE-2013-1493. ... The jar that exploited CVE-2013-1493 dropped a 9002 RAT with a MD5 of 42bd5e7e8f74c15873ff0f4a9ce974cd. ... The exploit site at sunshop[.]com[.]tw previously hosted a different malicious jar file on April 2, 2013. This jar file had a MD5 of 51aff823274e9d12b1a9a4bbbaf8ce00. It exploited CVE-2013-1493 and dropped a Poison Ivy RAT.
The java exploits were packaged as two different jar files. One jar file had a MD5 of f4bee1e845137531f18c226d118e06d7 and exploited CVE-2013-2423. The jar that exploited CVE-2013-2423 dropped a 9002 RAT with a MD5 of d99ed31af1e0ad6fb5bf0f116063e91f. This RAT connected to a command and control server at asp[.]homesvr[.]linkpc[.]net.
